Air Conditioned Seat Swap help needed

[Extinct]

So  I am swapping in a set of air conditioned seats from a 2010 Suburban (needed some wiring diagrams) in to my 08 LTZ. Determined that GM in their obsessive cheapness decided to make two different wire harnesses for heated vs air conditioned seats with the AC seat harness having 6 less 3 ft 18 gauge wires. Oh the savings! Anyway, a quick trip to the junkyard solved that issue. Now that I have all the wires I have an issue with the cool button not working. All the heat buttons work correctly and show up on my scanner (Foxwell NT680) as communicating with the memory module which controls the commands to the climate control seat module, but the cool button does not. I am wondering if this is programming issue between the mem seat module and the truck. The seats, door switches, and modules all came out of the Suburban so they all worked together before, but of course my LTZ did not have cooled seats from the factory. Wondering if I have a bad module or if it needs to be programmed by a Tech 2 or other GM programmer. Most interested to hear from people with either firsthand knowledge or ideally GM techs who could take a look at their trucks and let me know the best route to move forward. I am considering swapping in a different mem seat module to see if that is the issue with communication.

Picture for attention - I had the centers recovered in Alcantara from Relicate.
